Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened. In 1966, human error and turbulence combined to bring a plane down over Mount Fuji.

“Turbulence is serious if you are not tethered down in the airplane. It's serious from an internal perspective but it's not harmful to the airplane. So, when people get frightened in turbulence, as long as they're buckled, and there's nothing around them that's going to fly around,” they are safe, explains Kiernan.
Severe turbulence causes large and abrupt changes in altitude and/or attitude and, usually, large variations in indicated airspeed. The airplane may momentarily be out of control.Occupants of the airplane will be forced violently against their seat belts.
If a plane is flying along at a constant speed and height, then suddenly the headwind reduces, or it enters a descending column of air, this can cause the aircraft to suddenly descend, Gratton explained.
According to the FAA's Airplane Flying Handbook (8-18), for landing in turbulent conditions, use a power-on approach at an airspeed slightly above the normal approach speed. This provides for more positive control of the airplane when strong horizontal wind gusts, or up and down drafts, are experienced.
From a practical point, no, a modern airliner will not lose a wing due to turbulence. Modern airlines are very tough and designed to withstand extreme turbulence. In theory, it might be possible. But to my knowledge, it has not happened to any jet airliner.
Should you be scared of turbulence? The short answer is no, and rest assured that the pilots know how uncomfortable turbulence can make passengers feel. And know that no aircraft has ever crashed because of turbulence. Turbulence has not caused an airplane to crash, Biddle said.
DENVER (CBS4) – Colorado and the Rocky Mountains are among the worst areas for turbulence in the United States. It's a problem that injures dozens of passengers and crew members nationwide every year.
While pilots can't actually see turbulence, they often know what is coming up, thanks to reports from other planes, weather reports, and radar equipment. However, clear air turbulence (severe turbulence occurring in cloudless areas) can sometimes catch pilots off guard.
Winter has strong winds and blizzards, and summer's hot heat can create unstable air, thunderstorms, and tropical storms. That means flying during the holidays often means more turbulence than other times of the year. So if possible, avoid flying between December and February or June and August for a smoother flight.
Usually the pilots will leave the autopilot engaged. In small airplanes with limited autopilots, it is better to fly manually, but with more sophisticated airplanes the autopilot is a valid option in turbulence. Severe turbulence is actually very rare.
When pilots encounter turbulence, the speed is reduced to turbulence penetration speed Vra. This speed varies from aircraft to aircraft and is provided in the aircraft documentation. The speed for Vra changes with altitude until it changes to a constant Mach number.
Sometimes it's unavoidable to fly through light and moderate turbulence, but rest assured your pilots are working to find smooth air. If they encounter severe or extreme turbulence not forecasted, pilots will quickly climb or descend to a safe and smooth altitude.”
Except that, in all but the rarest circumstances, it's not. For all intents and purposes, a plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket. Conditions might be annoying and uncomfortable, but the plane is not going to crash.
Clear air turbulence forms like pancakes, so changing altitude is a suitable means of avoiding clear air turbulence. These are the main types of turbulence. Another source of turbulence is wake vortex turbulence which comes from an airplane's wings slicing through the air.
The worst seats on an airplane for turbulence are the jump seats in the back of the plane, where the flight attendants sit, followed by the passenger seats towards the back of the aircraft.
Even with turbulence, air travel is still the safest option
First, turbulence has not caused an airplane to crash for over 50 years. So, the chances of you being on the first plane to do so in almost half a century are slim to none.
Avoid wake turbulence by flying far enough behind other aircraft. Adhere to the ATC spacing buffer, especially when taking off or landing behind a “heavy” or “super” aircraft. Pilots can also avoid wake turbulence by flying above, below, or to the side of the path taken by other planes while at cruise altitude.
The odds of a plane crashing are not common – at least not nowadays. A rough estimate of the probability of an airplane going down due to an emergency is about 1 in 11 million, meaning it would take us quite a few lifetimes before actually experiencing a plane crash.
Periods of turbulence last an average of only 10 to 15 minutes, though it may seem like an eternity. Dr. Chris Manno, a pilot, professor, author, and current Boeing 737 captain for a major U.S. airline, is trained to deal with turbulence, but notes that airplanes are just as primed to take whatever weather is ahead.
